Unfortunately this change broke boot on some systems that used an
initrd which does not include the newly created crct10dif modules.
As these modules are required by sd_mod under certain configurations
this is a serious problem.

This patch adds unaligned buffer tests for hashes.

The first new test is with one byte offset and the second test checks if
cra_alignmask for driver is big enough; for example, for testing a case
where cra_alignmask is set to 7, but driver really needs buffers to be
aligned to 16 bytes.

<content type='text'>
This reverts commit cf1521a1a5e21fd1e79a458605c4282fbfbbeee2.

Instruction (vpgatherdd) that this implementation relied on turned out to be
slow performer on real hardware (i5-4570). The previous 8-way twofish/AVX
implementation is therefore faster and this implementation should be removed.

Converting this implementation to use the same method as in twofish/AVX for
table look-ups would give additional ~3% speed up vs twofish/AVX, but would
hardly be worth of the added code and binary size.

These are simple tests to do sanity check of CRC T10 DIF hash.  The
correctness of the transform can be checked with the command
	modprobe tcrypt mode=47
The speed of the transform can be evaluated with the command
	modprobe tcrypt mode=320

Set the cpu frequency to constant and turn turbo off when running the
speed test so the frequency governor will not tweak the frequency and
affects the measurements.

<content type='text'>
Patch adds AVX2/AES-NI/x86-64 implementation of Camellia cipher, requiring
32 parallel blocks for input (512 bytes). Compared to AVX implementation, this
version is extended to use the 256-bit wide YMM registers. For AES-NI
instructions data is split to two 128-bit registers and merged afterwards.
Even with this additional handling, performance should be higher compared
to the AES-NI/AVX implementation.
